Accurate elevation reference points are essential for ensuring consistency in design, excavation, and structural alignment. This paper presents a comprehensive engineering framework for benchmark establishment and utilization in topographic surveys. It includes geodetic control principles, leveling techniques, error propagation analysis, and digital survey integration using GPS and total station systems. Mathematical models for elevation accuracy, error adjustment, and least squares optimization are introduced. The study shows that improper benchmark management can lead to vertical alignment errors exceeding 10–15 cm in large-scale construction projects. The findings emphasize the importance of stable benchmark systems in ensuring precision in earthwork, road construction, and building projects, particularly in complex terrains such as Bali. ABSTRAK (INDONESIA) Benchmark (BM) adalah titik referensi penting dalam survei topografi untuk menentukan elevasi tanah. Paper ini membahas konsep dan fungsi BM dalam pekerjaan konstruksi. 1. INTRODUCTION (ENGLISH) Topographic surveying is the foundation of all construction engineering activities. Benchmarks serve as reference points for elevation control and spatial accuracy. In regions like Bali, where terrain varies significantly, proper benchmark systems are essential to avoid construction errors. 1. PENDAHULUAN (INDONESIA) Survei topografi membutuhkan titik acuan yang disebut benchmark (BM). 2.
